i To all 'whom t may concern:

Be it known that l, EDWARD R. TISCHER, a citizen of the United States, residing at Houston, in the county of Harris and State of Texas, have invented certain newand useful improvements in Gins, of which the following is a specification.

This invention relates to new and useful improvements in a gin.

One object of the invention is to provide a device of the character described, which is specially adapted for the -purpose of ginning cotton and other similar fibrous materials.

Another object of they invention is to provide a lgin whereby the fiber will be readily stripped from the seed without injury to said fiber, provision being made for` the .fiufiing of the fiber before it is delivered from the gin to the compress.

A further feature of the invention resides in the provision of means for discharging he seed after they have been freed of the int.

A still further feature ofthe inventionresides in the provision of means for separating the motes and other small foreign bodies from the fiber. i

With the above Aand other objects in view, the invention has particular relation to certain novel features of construction, operation and arrangement of parts, an example of which is givenqin this specification and illustrated in the `accompanying drawings, wherein:

Figure 1, is a rear view of thedevice, showing the casing of the fluffer roller removed.

Fig. 2, is an end view.

Fig. 3 is an end view as viewed from the opposite end to that shown in Fig. 2.

Fig. 4, is avertical sectional view.

Fig. 5, is an enlarged fragmentary side elevation of the ginning roller, and

Fig. 6, shows an end view of the stripper roller.

Referring now more particularly to the drawings wherein like Inumerals of reference designate similar parts in each of the figures, the'numerals 1, 1, refer to the end members of the casing, which are mounted upon a suitable base, and which are provided to support the operative mechanism. Mounted upon the transverse shaft 2, which is rotatable in suitable bearings, in the upper part of the casing, is,` the ginning roller 3. This roller is formed of a drum supported on the shaftby suitable spiders. riphery of the drum has parallel spirally arrangedv grooves 1, 4, spaced a suitable distance apart, and between them there are parallel spiraled rows of plugs 5, 5, which are formed of cork or other similar material. This drum is driven throughthe pulley 6, fixed upon one end vof the shaft 2, and fixed upon the other end of said shaft, there isa large pulley 3 alined withthe smaller pulley 9,1which is fixed upon the end of the Vtransverse shaft 10.r @perating over these last-mentioned pulleys and transmitting rotation from the former to the latter, there is a belt 11. The' shaft 10 is rotatably mounted in suitable bearings carried by the end members 1, 1, and within the casing and underneath the ginning roller there is a cylindricalv fan 12, fixed -upon said shaft,

ysaid fan being formed ofv a` cylindrical drum which is fixed upon said shaft through suitable spiders, and said drumhas the radiating blades 13, spaced a suitable distance apart, and extending from end to end of the drum. The fan is inclosed in front and beneath by the casing, but is exposed in the rear, and leading from the front part of the casing at its bottom, there is the discharge outlet14, through which the lint is discharged from the gin.

Mounted-'n the casing beneath and in the rear of theginning roller, and in rolling contact therewith, there is the transverse fiuifing rollerl, which is fixed upon the transverseshaft 16. This fluiiing roller is composed of a foraminated drum which is fixed on the shaft by means of suitable spiders. One end of the shaft 16 has the sprocket wheel 17, fixedl thereon which is driven through the sprocket chain 18, from thesprocket wheel 19,A which is fixed on a. sleeve 20. This sleeve is loosely mounted upon one end to the transverse shaft 21, which' is rotatable in suitable bearings in the end members 1, 1, and the sleeve 20 is rotated through the pulley 22, which is fixed The pethereon, and which, in turn, is rotated by and the' gearing is such that the iuiting roller will rotate much more rapidly than the ginning roller.

The numerals 25, 25, designate curved arms which are fixed at their lower ends to the transverse shaft 21, and whose upper ends are formed into bearings in which the shaft 26 rotates. This shaft has the stripper roller 27, fixed thereon, and the shaft is rotated through a sprocket chain 28, which operates over the sprocket wheel 29, which is' fixed on the sleeve 20, and the alined sprocket wheel 30 which is iXed on the corresponding end of the shaft 26. The stripper roller has a plurality of projecting beaters 31, which are preferably 'formed ot rawhide, leather, or some similar tough material, and are pivoted at their inner ends to said roller, but are held in radiating positions by centifugal torce when the machine is in operation. Fixed at its respective ends to the corresponding arms 25, and eXtend ing from endr to end or the ginning roller, there is the curved shoe 32, which partially surrounds the ginning roller in the rear, and

whose upperedge'is retracted or bent back, forming" a stripper edge 33, adjacent the ginning roller;

The seed cotton is :ted tothe ginning roller 'through the hopper 34, and is carried around by said roller against the stripper edge 83. The spiraled grooves a, will engage with the lint, and carry the sameunderneath the shoe 32, the cork plugs 5 also engaging with the lint, by friction, and carrying the same aroundfunderneath the shoe, and stripping the lint from the seed, the seed being arrested by the stripper edge 33. Meanwhile the rapid rotation of the stripper roller 27 will carrythe beaters 31 against the seed and said seed will be thereby treed from the lint and forced out over the shoe and the' lint will be partially iued thereby. The lint will then be carried by the ginning roller therearound and will pass between the ginning roller and the rluiiing roller, the rapid rotation of the latter of which will fluit the lint andl reduce it to a soft flui'y mass which will be delivered to the cylindrical fan 12, the blades oi' which will carry the limit around' and force it out through the outlet 14. The rapid rotation of the fan 12 will cause a discharge of the motes and other small foreign particles by centrifugal force out through the opening'in the casing behindsaid tan.

Fixed to one end ofthe shaft 21, there is a manual lever 35, through which said shaft may be turned, and the arms 25 and the elements carried thereby, may be adjusted toward and from the ginning roller. This manual lever` is provided with a rack-anddog arrangement 36, of the well known type through which it may be locked in any desired position. By vthis means, the strip-J ping roller 27 and the shoe 32 may be adjusted relative to the ginning roller, or may be withdrawn wheni it is desired to gain access to the rear part of the' said roller.
